Based in Houston, USA, Paul Tube Fittings is a well-respected manufacturer and supplier of high-performance Stainless Steel Ball Valves, serving a variety of industrial needs. The company prides itself on quality, reliability, and innovation, providing precision-engineered valves that guarantee smooth flow control and leak-proof operation, even under high pressure and temperature. Crafted from top-grade stainless steel, these ball valves boast impressive corrosion resistance and mechanical strength. Paul Tube Fittings caters to essential industries like oil & gas, petrochemicals, pharmaceuticals, and power generation, offering both standard and tailored solutions to meet rigorous operational and safety standards.
Stainless Steel Ball Valves are generally constructed from materials like SS 304, 316, or 316Ti, depending on their intended use. These alloys consist of iron with 16–18% chromium, 10–14% nickel, and for 316/316Ti, an additional 2–3% molybdenum and titanium to boost corrosion resistance and thermal stability. Mechanically, they deliver high tensile strength (around 515 MPa), a yield strength of 205 MPa, and outstanding resistance to pitting and crevice corrosion. These characteristics ensure durability, effective pressure containment, and reliable shut-off capabilities, even in harshly corrosive or high-temperature settings.
